The H.K. Brick-Laying & Construction Trade Workers’ Union H.K. Brick-Laying & Construction Trade Workers’ Union is one of the unions of professional applicators and workers among the Hong Kong construction industry. In September 2013, their committee and members visited the OPTIMIX manufacturing plant. The Union shared their practical experience on sites and OPTIMIX provided the latest cementitious dry mortar technologies and material trials for the Union.

OPTIMIX invited the senior management and their colleagues, of the newly established subsidiary of the New World Group, Hip Seng Construction Co. Ltd. to visit its plant and share its material technology, in pre-bagged cementitious dry mortars. OPTIMIX's Technical Director, Ir. Raymond Wan, introduced the latest dry mortar manufacturing technology and the R&D results in advanced cementitious plastering, tiling, and self leveling flooring systems. Hip Seng shared certain cases that occurred on their projects and were interested in how Optimix products could assist them to assure their application quality on sites. The guests were also invited to visit OPTIMIX's laboratory to understand the rigorous in house quality control of OPTIMIX products. Both OPTIMIX and its guests have exchanged material technologies and experiences during this plant visit.

Guangzhou International Finance Center (Guangzhou West Tower), located at the core of Pearl River New City, southwestern financial business district, is a landmark on the axis of Guangzhou. The project has high quality requirements for the underground parking lot renovation. After the stringent performance comparison of all the major brands by the owner and main contractor, they confirmed to use OPTIMIX products. The application was challenging, since the Four Seasons Hotel continued to operate as normal above the underground renovation area, such that the construction noise, generated by floor grinding machines, had to be maintained to a minimal level so as not to affect the operation of the hotel. Accordingly, the applicator had to manually pre-treat the uneven surface of the existing ground before the application of self leveling underlayment. After several days of effort, the renovation was successfully completed. Although the application surface was treated manually, the OPTIMIX product performed well and was finished to level and smooth, without experiencing any problems evident in traditional floor screeds, such as lamination, weakness, powdering, etc. Product used: •  OPTIMIX SF818 Self-Leveling Underlayment

Silver Tower, located in the center of Shanghai's bustling Huaihai Road shopping district, is an integrated property development including a 28 storey service apartment tower and a 16 storey office tower, together with a 5 storey shopping arcade. The property was acquired by Maple Tree Group of Singapore in 2011. The original waterproofing material on the rooftop was a traditional sheet membrane type, which had degraded with age, leading to the interfaces becoming delaminated. During the typhoon season of 2012, the buildings faced numerous leaking problems due to the failure of the existing sheet membrane waterproofing. The property managers of Silver Tower sought an effective replacement system to achieve a secure remedial solution for the waterproofing. After a series of technical assessments on the material’s properties and performance, they chose an OPTIMIX high performance system to completely replace the existing waterproofing system. The owner and the property management company was wholly satisfied with the outstanding material quality and performance achieved by the OPTIMIX system. Product Used: •  OPTIMIX WP569 Waterproofing Slurry (Flexible)
